Research of Real-time Recording Technology in Airborne Video Data Recording Based on Synchronous Processing

在机载航电系统中,为了能够实时、无损地记录显控子系统传来的实时视频数据,最大程度地保留原始视频的图像质量,研究了基于多任务同步处理的机载视频实时记录技术。通过详细阐述接收任务和存储任务的设计方法以及分析两者的同步策略,直观展示了基于同步处理的机载视频实时记录技术的实现架构。同时依托多核处理器平台来设计真实的测试场景,并在实际机载嵌入式系统中部署运行,其结果证实了基于同步处理的机载视频实时记录技术的正确性。

In order to recording the video data of display subsystem in airborne avionics system nondestructively and in real time,a real-time recording technology based on synchronous processing is introduced in this paper.This paper shows the real-time recording architecture by elaborating how to design receiving task and storing task,and the synchronous strategy between them.In the meantime,by means of designing actual test scenario on multi-core processors and deploying the real-time recording technology in real airborne embedded system,the results demonstrate the validity of the real-time recording technology based on synchronous processing.
